ChangJiang Connectors Co.,Ltd
The good news | warm congratulations on the CJTCONN
In order to establish our hi-tech industry and promote the rapid development of hi-tech enterprises, the ChangJiang connector should adhere to "pioneering and innovation, green environmental protection and sustainable development" and wisdom. For more than 20 years, CJTconn, under the leadership of the company, has led the outstanding members of the company to continue to forge ahead. With the support from all walks of life, the ChangJiang connectors was awarded the certificate of high-tech enterprise jointly issued by Shenzhen science and Technology Innovation Committee, Shenzhen Municipal Finance Committee, Shenzhen National Taxation Bureau and Shenzhen Local Taxation Bureau in October 31, 2017
With the improvement of social living standard, automobile as a substitute tool is gradually popularized. The popularization of automobile drives the development of automobile parts. The automobile connector is an indispensable part. CJT will show you the automobile connector.
Automobile connector is a kind of component that electronic engineers often contact. Its function is very simple: in the circuit is blocked or isolated between the circuit, set up a bridge of communication, so that the current flow, so that the circuit to achieve the intended function. The form and structure of automobile connector are ever-changing. It is mainly composed of four basic structural components: contact parts, shell (depending on the variety), insulator and accessories.
Four basic structural components of automobile connector
1、 Contact parts are the core parts of automobile connector to complete the electrical connection function. Generally, the contact pair is composed of positive contact and negative contact, and the electric connection is completed by inserting the negative and positive contact.
The positive contact is a rigid part, and its shape is cylindrical (round pin), square (square pin) or flat (insert). The positive contacts are generally made of brass and phosphor bronze. The female contact, i.e. the socket, is the key part of the contact pair. It relies on the elastic deformation of the elastic structure when it is inserted with the pin to produce the elastic force to form close contact with the male contact and complete the connection. There are many types of jacks, such as cylinder type (slot, necking), tuning fork type, cantilever type (longitudinal slotting), folded type (longitudinal slotting, 9-shaped), box type (square jack) and hyperboloid spring jack.
2、 The shell, also known as the shell, is the outer cover of the automobile connector. It provides mechanical protection for the inner insulating mounting plate and the pin, and provides the alignment when the plug and the socket are inserted, so as to fix the connector to the equipment.
3、 Insulator, also known as automobile connector base or mounting plate, is used to arrange contacts according to the required position and spacing, and to ensure the insulation performance between contacts and between contacts and shell. Good insulation resistance, voltage resistance and machinability are the basic requirements for selecting insulating materials to be processed into insulators.
4、 Accessories, accessories are divided into structural accessories and installation accessories. Structural accessories such as clamp ring, locating key, locating pin, guide pin, connecting ring, cable clamp, sealing ring, gasket, etc. Install accessories such as screws, nuts, screws, spring rings, etc. Most of the accessories are standard parts and general parts.
It is these four basic structural components that enable the automobile connector to act as a bridge and operate stably.
